What is the origin of the idiom "shed light on something" and when to use it?
The idiom "shed light on something" comes from the literal act of illuminating something to make it visible or clearer. Historically, before the advent of electric lighting, people used candles, lanterns, or other sources of light to see in the dark. This practical need to illuminate objects and surroundings naturally extended into metaphorical use. Thus, "shedding light" on a subject came to mean providing insight or clarity, helping to understand or reveal information that was previously obscure or hidden.
